Another Freakin VLSD thread - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

240sxhed · 06-13-2005, 08:29 PM

Ok heres the deal, ive been getting mixed answers to this question. My car leaves two stripes when doing a straight burn out and when sideways (IE Turning the wheel to one side and dropping the clutch and spining around, I did this today in a parking lot).
However a friend who is a mechanic said to jack it up and spin the wheel. I did there was some resistance to turn the wheel but the other wheel did not move. He then said this meant open diff.
However another friend who is a mechanic said this deffinately means VLSD and the other tire not movein simply meant it was not locked. Also a friend with a 350Z that deffinately has a VLSD did the same test and his opposite wheel hardly moved at all either.
whats the deal here?

thanks alot guys.

If you have vlsd, it should still move the other wheel when jacked up. Either you guys had VLSD and it is now blown or you guys have open diff. It is possible for both wheels to spin on a burnout with an open diff.

You sure that 350Z had the lsd? AFAIK, only the track models came with it. I have an LSD in mine and both wheels spin in the same direction with little effort.

yeah im sure..... all models of 350Z except for the base model come standard with a VLSD. He has the performance model.

In order for the other wheel to spin, you would have to spin the viscous sludge in the diff to rotate the other wheel's plate. Spinning the wheel by hand is probably not enough torque to do so.

Your mechanic friend is probably used to domestics with lockers and hardcore posi. Or you have an open diff.

I thought with open diff the other wheel spins opposite direction when you turn one wheel by hand?

infinitexsound · 06-14-2005, 02:37 AM

that is true also.......... maybe ur diff is shot

True, spinning one wheel on my open diff. caused other wheel to spin opposite direction.

Spinning one wheel by hand on my J30 viscous causes other wheel to spin in same direction (rear lifted of course). Sounds like you have the viscous but it's on its way out maybe? Good luck.

if the car is what is listed in your sig and you didnt put the vlsd there, then no.

anyhow, there are a ton of easy ways to figure it out on the s13, search

haha, the only thing that is on my car that is deffinately an 89 is the vin, nothing i mean nothing on my car came on an 89. down to the smallest interior differences. All from 91 and up. It is reconstructed. so who knows

, im leaning towards an old VLSD that is on its way out.
